when i'm playin back my datalog with wideband hooked up. the a/f window goes back and forth, but does not display any values in the cells. can anyone tell me why. did i not check an option that tells it to do so?

or does the car actually have to be on and in motion, for this feature to work. another words this won't work simply by looking at a saved datalog??

i assume its for WHEN you want it to start logging A/F's? so for example anything above 2% throttle, then it will start recording, and anything below 2%, it stops recording/logging. am i even close? haha
